ABSTRACT:
Printable or otherwise encodable labels are provided with features that allow an observer to judge the validity of a marking made with the label. The labels comprise a handleable support sheet and a fragile easily tearable heat-softenable film adhered to the support sheet. A visible or machine-sensible component, such as a printed image, extends over the area of the film, and the film extends beyond at least one edge of the support sheet and carries a layer of adhesive so that it can be adhered to an article that is to be marked. Upon removal of the label from an article to which it has been applied as a marking, the extending portion of the film will tear and remain adhered to the article. The removed label will not be useful if applied to another article with a portion missing; and if an attempt is made to superpose the label with the torn portion of film remaining on a different article, mismatching of the label and torn portion, e.g., through mismatching of the visible or machine-sensible component, will reveal the transfer.
